Description

Chiseling and drilling machine

Technical Field

The invention relates to tunnel construction equipment, in particular to a roughening and drilling machine.

Background

In the tunnel construction process, the secondary lining concrete is subjected to scabbling treatment so as to improve the adhesive force of the concrete surface and ensure that the construction surfaces in two construction stages are firmly bonded. At present, the tunnel roughening method mainly comprises manual roughening, mechanical roughening by a roughening machine and roughening by a special roughening machine for tunnels. The manual scabbling mainly is that the workman uses miniature hand-held type bush hammer or electric pick (or hydraulic pick) to chisel the hair, and this kind of chisel hair mode inefficiency, intensity of labour are big and can not guarantee the chisel hair quality, and the quality of chisel hair can not lead to two construction faces to bond insecure not up to standard, the condition such as infiltration or fracture appears. The machine-mounted chiseling machine is generally mounted on an excavator or a simple truss for chiseling, and due to the limited space of the tunnel, the construction mode can affect the access of other tunnel construction machines. The chiseling part of the existing tunnel special chiseling machine is generally matched with a tunnel lining curved surface with a certain size. This kind of chisel hair machine has fine chisel hair effect when being used for the tunnel chisel hair of this size, but when being used for the tunnel chisel hair of other different sizes, chisel hair part and tunnel curved surface cooperation do not go up, can appear the problem that chisel hair quality is not up to standard. Therefore, tunnels with different sizes are specially matched with a roughening machine with a corresponding size, and the construction cost of the tunnels is greatly increased.
